Product Overview

The Excess Pro is a cassette-style rear hub designed for 20" BMX race wheels.

Best suited for competitive racing where reliable engagement and low maintenance are prioritized. Optional Center Lock adapter allows disc brake rotor mounting for riders transitioning from rim brakes. Standard 3/8" axle fits most race frames and dropout configurations.
